Child Tax Credit Now Requires Valid SSN for Parent and Child
New eligibility rules tighten the Child Tax Credit for 2026, requiring both parent and child to have valid Social Security Numbers. The change affects mixed-status families even as the credit amount rises to $2,200 per child.
The IRS has implemented a new requirement for claiming the 2026 Child Tax Credit that affects eligibility beyond the well-known increase in dollar amounts. Parents and guardians must now ensure that both they and their qualifying children have valid Social Security Numbers to claim the credit.
Who Is Affected?
- Married couples filing jointly must have at least one spouse with a valid SSN
- Each child claimed must also possess a valid Social Security Number
- The refundable portion (Additional Child Tax Credit) remains capped at $1,700 per child, unchanged from prior years
While the credit amount increased from $2,000 to $2,200 per qualifying child under the One Big Beautiful Bill, this new SSN requirement creates a significant eligibility barrier for mixed-immigration-status families. Previously, parents without SSNs could still claim the credit using valid Individual Taxpayer Identification Numbers (ITINs). That option is now restricted.
What This Means for Foreign Residents and Expat Families
If you're an expat or foreign resident with dependents in the United States, or if you sponsor qualifying children while maintaining residence abroad, you'll need to verify that both you and each child have valid Social Security Numbers before filing your 2026 return (due April 15, 2027). Families with mixed immigration status—some members with SSNs, others with ITINs—should consult a tax professional to understand how this change affects their eligibility. The $2,200 credit is substantial (potentially a $1,700 refund per child), so confirming your status early avoids costly filing delays or corrections.
